夜久 月子

Tsukiko is the first female student to attend Seigetsu Academy and is often pursued by many of the other male students. She is part of the Student Council, the Archery Club, and is also on clinic duty. She always strives to do her best, which sometimes results in overworking herself to the point of collapsing.

She has a total of 12 potential love interests, although this number increases in the After Season games due to the introduction of new characters and the ability to date minor characters.

Tsukiko is drawn without eyes in the original Starry☆Sky. After the release of After series and all game releases, player have the option to have Tsukiko's eyes included in CGs or not.
